Remarks

Dolby HX PRO system provides improved linearity in the upper frequency range during recording. Separate Dolby B and C systems on each deck allow individual adjustment of noise reduction during simultaneous recording, relay recording and normal speed dubbing. BIAS calibration allows the optimum bias current to be set for each tape type. Quick reverse function for switching the running direction during recording and playback with extremely low interruption. Automatic tape type detection during recording and playback. Multi-AMS, Blank Skip and Memory function for convenient title retrieval. Relay function for successive recording and playback for both decks. Automatic playback start function after tape rewind. Timer-controlled recording and playback when a separately available timer is connected. Synchronous dubbing at either normal or high speed. Simultaneous recording for recording the same signal source with both decks. Overdubbing level adjustment capability allows the recording level to be changed when dubbing at normal speed. Fine adjustment of tape speed during playback and dubbing at normal speed (deck A). Fluorescent level indicator is very accurate and easy to read. Digital linear counter in minutes and seconds shows the elapsed recording and playback time of each deck.

Both drives work completely separately from each other. For example, you can record with one while playing back with the other. Or you can copy parts from one drive to the other and dub each. A light touch with the hand is detected and the flaps close quickly and very quietly, motor-controlled. Many functions are hidden behind the aluminium flap. Both digital counters have memory function. The tape speed is infinitely variable. When copying from drive to drive, the level can be readjusted. The reverse mode can be switched, as well as the switching of both drives in series. As it should be for a studio device, separate biases are adjustable, and the balance is adjustable.
